MACHINE FOR CLEANING TEXTILE FIBERS, IN PARTICULAR COTTON FIBERS.

Application filed December 11, 1913.

To all whom t may conce/ra:

Be it known that I, ANDREAS S'rnnirr, a citizen of the Republic of Switzerland, residing at Telfs, Tyrol, Austria-Hungary, have invented new and useful Improvements in Machines for Cleaning Textile Fibers, in Particular Cotton Fibers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same, reference being had to the accompanying drawings, and to letters or iigures of reference marked thereon, which form a part of this specification.

This invention relates to an improved machine for cleaning textile fibers, in pai'- ticular cotton fibers.

According to this invention movable members provided with teeth are pivoted on a rotary supporting or carrying member, which members are supported during operation radially from the carrying member by centrifugal force and are thus driven against the material to be treated in order to beat, clean and card the same.

Several forms of carrying the invention into effect are shown by way of example on the accompanying drawings in which- Figure 1 is an elevation, partly in section,

i of the cleaning machine, Fig. 2 is a vertical section on the line c-c of Fig. 1; Fig. 3 shows a side view of a. modification of the supporting portion of the machine with the members pivoted thereto kin section; Fig. 1 shows an end view of Fig. 3, Figs. 5 and (3 show views corresponding to those shown in Figs. 3 and il, respectively, of another modification, and Figs. 7 and 8 show a further modification-` In the machine shown in Figs. 1-2, 1 denotes the frameof the machine. 2 is a slotted carrier feeding the material to be treated into the'machine. This cloth passes over several notched rollers of which there is shown only the roller 3 in Fig. 1. The latter is driven by' the main driving shaft 4, there being provided for this purpose avbelt drive 5, gearing 6, 7, 8, 9 and 10 and a belt drive 1.0%.

The frame 1 has a number of slotted guides 11 for the rods 12 of the laps 18. In the present instance there is also shown only one of these guides 11. The laps 1.3 are superposed in a known manner. Fig. 1 shows on the left hand side three such super- Speccation of Letters Iatent.

posed laps 13 of material to'be cleaned. 14 is a notched cylinder feeding the laps 13 toward the edge 16 provided on a troughshaped member 15. The toothed wheel 111a feeds the laps 13 toward the cylinder 14. The member 15 maybe connected to a known regulating device, which brings said member in such a relative position to the cylinder 14:, that the same volumes of material are continually fed through the channel 15 during a fixed time interval.

All the parts hereinb fore mentioned are already known, and they shall not be claimed as new.

Behind the cylinder 14: and the troughlike member 15 there is provided a cleaning apparatus consisting of several supporting members 18. These members 1S are mounted onto a shaft 19, driven by the main driving shaft 1 by means of a belt drive 20. In order that said device may be inspected there is pivotally mounted on the frame 1 cover 21. Below the cleaning device there is arranged a grate 22. The dust and the dirt contained in the material to be cleaned fall through this grate 2Q into the lower part of the casing 1. y

In the arrangement illustrated in Figs. 1-2 each of these supporting members 18 is provided with four ear-like lugs or projections 23. Each of these projections carries a pin 21. On each pin Qllthere is pivotally mounted a yoke or frame 25, which consists of two hub-like parts 9,6 (Fig. 9.) vmounted on theA pin 21 and an outer part connected by two arms 27 with parts 26. This outer part is provided with teeth 28, which are of rectangular section. The outer face of these teeth is rounded in the manner shown in Fig.` 1, so that they increase in depth from the front to the rearv in the direction in which the shaft 19 is rotated.

l/Vhen the machine shown in Figs. l-Q is set in rotation, the yokes or frames 25 carried by the pins 241 are moved by centrifugal force so that they lie radially from the supporting members 18 and are driven against the material to be treated, which is fed to ward the edge 16 of the trough-like member 15 by the endless cloth 2 or the like, the wheel 14 and the cylinder 14, so that the material is beaten, cleaned and carded. The dust, dirt and the like fall thereby through the grate 22 downward. For the purpose of sucking up the waste there may be provided on the righthand side of Fig. 1 a ventilator or the like. ,The provision of pivotally mounted yokes or frames permits to attain the advantage, that the strokes or blows are not so hard as in a machine provided with projections or noses forming a whole with a drum. The machine shown in Figs. 1-2 provided with four supporting members forms a so-called opener or carder and it is particularly adapted to clean cotton.

In the modification shown in Figs. 3 and 4 the teeth 28 of the frames 25 are formed increasing rapidly in width toward their base and they have a concave sided trianguf lar cross-section in a plane at right angles to the plane of rotation of the shaft, the teeth inclosing between them grooves of a convex sided triangular cross-section.

In the arrangement shown in Figs. 5 and 6 each of the supporting members 18 s provided with onlywtwo lugs or projections 23 and the teeth of the yokes 25 have a truncated triangular cross-section, while each pair of these teeth incloses a groove having also a truncated triangular cross-section. If the yokes` or frames are pivotally connected to a carrying body in the form of'a disk or flier provided with two projections or ears a. so-called beater or scutcher is obtained.

In Figs. 7 and 8 a yoke is shown having pointed teeth 28 of cone-shape suitablyV spaced one from the other.

The form of the teeth of the yokes 25 is adapted to the conditions of the material to be treated, and it is evident, that the teeth may also have a different form from that illustrated on the accompanying drawings.r The paths of travel of one set of teeth onthe pivotally attached members shown in the figures may be displaced relatively to another set, by displacing said members, so

that the corresponding teeth of these mem-r bers may each deal with a differentlayer of material and consequently a better cleaning action is obtained.

It may also be pointed out that more or less than four movablemembers may, lif desired, be pivoted to each supporting body and that the constructions of the teeth of the member 27 may be varied according to the material operated, so that the best resuits may be obtained. In the first instance Y the cleaning apparatus may then form a drum.

I declare that what I claim 1s: 1. In a machine for cleaning textile fibers,

a beater for opening and carding7 cleaning and beating the fibers and acting upon the latter at a point as far away as possible from the clamping point of the fibers, comprising a rotatable shaft, a plurality of arms connected thereto and adapted to lie radially thereto under the action of centrifugal force,`and a plurality of teeth on said members deeper in the front than at the rear.
